Debiased recommender models have recently attracted increasing attention from the academic and industry communities. Existing models are mostly based on the technique of inverse propensity score (IPS). However, in the recommendation domain, IPS can be hard to estimate given the sparse and noisy nature of the observed user-item exposure data. To alleviate this problem, in this paper, we assume that the user preference can be dominated by a small amount of latent factors, and propose to cluster the users for computing more accurate IPS via increasing the exposure densities. Basically, such method is similar with the spirit of stratification models in applied statistics. However, unlike previous heuristic stratification strategy, we learn the cluster criterion by presenting the users with low ranking embeddings, which are future shared with the user representations in the recommender model. At last, we find that our model has strong connections with the previous two types of debiased recommender models. We conduct extensive experiments based on real-world datasets to demonstrate the effectiveness of the proposed method.

In a world dominated by artificial intelligence, data, and ever-advancing connectivity technologies, it's hard to leave the'Internet of Things' out of a list of innovative and game changing technologies. In fact, IoT may be one of the most important technologies out there right now, as it is responsible for the success of many other technologies, like machine learning. As the market landscape evolves over the next several years, it's critical for businesses to monitor how things are changing. Some of the most successful businesses are the ones who think creatively about evolving technologies. Coming up with ideas for innovative ways to use and combine these technologies together isn't possible without keeping an eye on these trends.

If you ask Alexa, Amazon's smart speaker, that she is spying on you. She replies, "I only send audio back to Amazon when I hear you say the wake word. For more information and to view Amazon's privacy notice, visit the help section of your Alexa app." This reply sounds so naive and gives little hint of the sea of data Amazon's smart speaker captures and stores. To understand the data collection size of'Echo' speaker, Dave Bryant, who has created and sold a multi-million dollar e-commerce store, requested all of his personal data from Amazon.

The University of the Philippines recently opened a doctorate degree in the National School of Engineering for Artificial Intelligence at their Diliman campus. According to the university's official press release, they created the course in hopes of "developing graduates who had the mindset to expand the field of artificial intelligence". We have the command bot Alexa, our iPhones have Siri, and some laptops have Cortana. There's even the new Google Home that can control our air-conditioner and lights! All those names we just mentioned are forms of Artificial Intelligence. It takes a lot of programming to create these bots.

We introduce a new dataset for conversational question answering over Knowledge Graphs (KGs) with verbalized answers. Question answering over KGs is currently focused on answer generation for single-turn questions (KGQA) or multiple-tun conversational question answering (ConvQA). However, in a real-world scenario (e.g., voice assistants such as Siri, Alexa, and Google Assistant), users prefer verbalized answers. This paper contributes to the state-of-the-art by extending an existing ConvQA dataset with multiple paraphrased verbalized answers. We perform experiments with five sequence-to-sequence models on generating answer responses while maintaining grammatical correctness. We additionally perform an error analysis that details the rates of models' mispredictions in specified categories. Our proposed dataset extended with answer verbalization is publicly available with detailed documentation on its usage for wider utility.

Have you ever dreamed of being your own boss or being able to work from anywhere in the world? I have a secret for you. This is possible if you become a virtual assistant. Virtual assistants are no longer just online secretaries. Employers are looking for virtual assistants that can update websites, create email newsletters, schedule social media posts and more.

It's a good time to stock up on travel-friendly accessories before your next trip. A number of Anker portable batteries, wireless chargers and other accessories are on sale, and you can save even more if you're an Amazon Prime member. Those who need to work while on the go can pick up Samsung's T7 Shield SSD for the cheapest price we've seen, while Samsung's Galaxy Buds Pro drop to an al-time-low price just days after the company announced the latest version of the earbuds in the Galaxy Buds 2 Pro. On top of all that, the Apple TV 4K is on sale for only $120 and you can pick up a base iPad for as low as $299. Here are the best tech deals from this week that you can still get today.

Digital transformation is no longer an inward tactic used to reform an organisation's operations; it's now a necessary undertaking sought out by CIOs and IT leaders. Recent developments have pushed organisations to embrace digitisation, causing the fourth industrial revolution and technologies such as artificial intelligence to go mainstream. Even though, according to Gartner, only 53 per cent of AI projects make it from prototype into production, companies can't ignore the benefits of successful AI implementation. Enhanced AI solutions such as the artificial intelligence of things (AIoT), conversational AI and machine learning (ML) are improving the future of digital transformation and offer more innovative ways than ever before to address business challenges. Today's AI solutions can be customised to address a company's unique set of challenges.

Amazon's Echo Show 15 comes with a digital photo frame picture that enables it to display only photos or artwork, uninterrupted by random Alexa skill suggestions, recipes or your schedule. Only the 15.6-inch had that feature, though -- until now. According to The Verge, the e-commerce giant has recently added its dedicated photo frame feature to all Echo Show Models in the US, the UK, Canada, Germany, France, Italy, Spain and Australia. The Verge says you can activate the slideshow by saying the voice command: "Alexa, start Photo Frame." Your smart display will then start a slideshow using the contents of your Amazon Photos and your Facebook account. It can also display a random selection of stock images if you've yet to upload your personal photos or have yet to link your accounts with the device.
